                    <p>Redis提供了多种强大的数据结构来处理列表数据的排序需求，从简单的List到专门的Sorted Set，再到复杂的Streams，每种方法都有其适用的场景和优缺点。</p>
                    
                    <p class="font-medium">关键选择因素包括：</p>
                    <ul>
                        <li><strong>数据规模：</strong>小数据集可以使用任意方法，大数据集需要谨慎选择</li>
                        <li><strong>排序频率：</strong>高频排序需求应优先考虑内置排序功能的数据结构</li>
                        <li><strong>排序复杂度：</strong>复杂排序逻辑可能需要应用层处理</li>
                        <li><strong>实时性要求：</strong>实时数据流处理需要Streams等现代数据结构</li>
                    </ul>
                    
                    <p>在实际项目中，最好的方法往往是根据具体需求组合使用这些技术。例如，可以使用Streams接收和缓冲数据，然后定期将数据转移到Sorted Set进行排序和查询，同时保留应用层处理复杂排序逻辑的能力。</p>
